UNITED STATES MARIE GREGG LIPPINOOTT, OF PHILADELPHIA, PENNSYLVANIA.

SAFETY-PIN.

SPECIFICATION forming part of Letters Patent No. 712,819, dated November4, 1902.

Application filed May 31, 1902.

To all whom, it may concern:

Be it known that I, MARIE GREGG LIPPIN- COTT, a citizen of the UnitedStates, residing in the city and county of Philadelphia, State ofPennsylvania, have invented a new and useful Improvement in Safety-Pins,of which the following is a specification.

My invention consists of an improvement in a safety-pin, the objectbeing to provide a construction that insures interlocking of the pinproper with the sheath and which also provides against the accidentaldisengagement of said parts.

Figure 1 represents a plan view of a safetypin constructed in accordancewith my invention. Fig. 2 represents an edge View of a modifiedconstruct-ion thereof. Fig. 3 represents a plan view of still anotherembodiment of my invention.

Similar letters of reference indicate corresponding parts in thefigures.

Referring to Fig. 1 of the drawings, A designates the shank of the pin;B, the usual spring-coil; O, the pin proper, and D the sheath. In saidFig. 1 I have shown the shank A as provided with deflected portions E,formed by bending the intermediate portion thereof in zigzag direction,while the pin" proper, O, is provided with the deflected portions F. Bybending the shank and the pin proper in the manner shown I find that/therigidity of the same is increased, or, in other words, that they possessless resiliency, so that the tendency to bend is reduced, likewise re-'ducing the tendency of the point of the pin to be disengagedaccidentally from the sheath. This tendency in the ordinary straight orSerial no. 109,590. (No model.)

curved pin is most apparent when a strain is placed upon the same, sothat it will bend and withdraw the pointed end from the sheath. It willalso be noted that the deflected portions are located outside of theordinary plane in which the pin and shank extendthat is to say, thedeflections are to the outside of the axis of the pin.

In Fig. 2 I have shown a modification of my invention, which consists indeflecting the pin laterally, as shown at G.

The modification shown in Fig. 3 differs from that shown in Fig. 1 inthat the shank A is straight or of the usual form.

Havingthus described myinvention, What I claim as new, and desire tosecure by Letters Patent, is

l. A safety-pin provided with a pin proper having integral coil andshank and having between the ends thereof indentations, each consistingof a deflection at an angle to the line through the ends of the pin andthe succeeding deflection back to said line, said indentations being ina plane outside of the plane through the pin and shank.

2. A safety-pin provided With a pin proper having-integral coil andshank, said shank andpin proper each having between the ends thereofindentations, each indentation consisting of a'deflection at an angle tothe line through the ends of the pin and the succeeding deflection backto said line.
